Questions & Answers about Quand est-ce que tu voyages ?
How do you use "est-ce que" with a question word like "quand" here?
What happens to the English word "do" from "When do you travel"?
French doesn't have a direct translation for the helper word "do" in questions. Instead, the phrase est-ce que (which literally means "is it that") does exactly the same job! It is just a tool used to turn a statement into a question.
Why does voyages end in an "s", and do I pronounce it?
Can I ask this same question without using est-ce que?
Yes! In casual, everyday speech, French speakers often drop it and put the question word at the very end, like this: Tu voyages quand ? (You travel when?). However, the version with est-ce que is the standard, safe way to ask questions in any situation.
